Abstract: A system for reducing artifacts when imaging under pulse-width modulated illumination. A controller captures, with an image sensor, images as frames of a video of a target in an environment in which the target is illuminated by a pulse-width modulated light source. In doing so, the controller sets a first parameter for the image sensor as a function of a light pulsation period of the pulse-width modulated light source to reduce artifacts in the images associated with the pulse-width modulation of the light source. Further, the controller determines whether residual banding artifacts resulting from the pulse-width modulation of the light source are unacceptable in the images captured with the image sensor. Additionally, the controller performs, in response to a determination that residual banding artifacts are present in the images, image processing to correct the residual banding. The system outputs the resulting images with reduced artifacts for viewing by a user.
